Array([0.1] => cr Object([priv_member:private] => 9)[0.5] => cr Object([priv_member:private] => 12)[0] => cr Object([priv_member:private] => 23))

例子 2. array_udiff_assoc() 例子

<?php$a1=array(0=>"Cat",1=>"Dog";,2=>"Horse");$a2=array(0=>"Rat",1=>"Horse";,2=>"Dog");$a3=array(0=>"Horse",1=>"Dog",2=>"Cat");print_r(array_diff_assoc($a1,$a2,$a3));?>

Array ( [0] => Cat [2] => Horse )

注: 注意本函數(shù)只檢查了多維數(shù)組中的一維。當然，可以用 array_udiff_assoc($array1[0], $array2[0], “some_comparison_func”); 來檢查更深的維度。
